SKYLIGHT.

SPECIFICATION forming part of Letters Patent No.-280,036, dated June 26,1883.

vented a new and useful Improvement in the Construction of Skylights andother Glazed Structures, of which the following is a specification.

This invention has for its object lightness combined with strength, aswell as to effect ually provide against leakage from storm or fromcondensation, and the drifting of snow into or beneath the structure.

My improvement relates to the construetion of the bar'or rafterconstituting the skeleton of the structure, and by which the glassplates are supported; and it consists, first, of the bar or raftercomposed of two curved plates of sheet metal placed back to back,curving outwardly at top and bottom, bent to form ledges or shouldersfor reception of glass plates, and beneath the same gutters for removingdrip resulting from condensation and leakage; second, in thecombination, with the bar thus constructed, of an under cap or moldingso appended as to give a finish, ornamental or otherwise, .to the underside of the bar or rafter, and to constitute a central or interiorgutter to more effectually secure against leakage third, in thecombination, with the bar of curved plates, of a cap of pliablemetalsuch, for instance, as lead strips-inserted down between the curvedplates, secured thereto, and adapted to be bent over above the glassplates to cover their edges and secure against leakage at that point;fourth, in the combination, with said bar of curved plates, of one ormore vertical inside plates for the purpose of giving additionalstrength to the bar, arranged between the two curved plates forming thebar, and extending upward and downward, as necessary for the strengthrequisite. The bar proper consists of the two curved plates joined, towhich, a when required, the under cap is added, and, when necessary forstrength, the in terior vertical plates are added, and also the pliableupper cap. Each of these additional parts may be combined with the barwithout the addition of either of the others, to suit the nature of thecase and my invention consists, further, in combining all the aboveelements together to constitute one bar, when so de- Application filedJune 16, 1882.

sired, for certain structures wherein greater strength is deemednecessary.

In the dr. wings, Figure 1 shows a section of skylight with slopingbars, ridge-bar, and

baseframe, the gutters of which parts are with a pliable cap-plate bentover the glass plates in finish, and the under cap added, portions alsobeing in perspective. Fig. 5 shows a cross-section of the bar withinternal vertisal plate and another form of cap used. Fig. 6 shows across-section of the bar with pliable cap, internal vertical plate, andunder cap, forming a complete combination of all the elements. Fig. 7shows a cross-section of the bar with pliable cap-plate, under cap ormold ing, and two internal verticalplates, showing how they may bedoubled. Bolts or rivets are shown in all the figures as a means ofuniting the parts. The cap-plate in Fig. 7, where it extends downbetween the glass plates and the two sides of the bar, is solid for theentire vertical portion, and not of two parts folded, as in the otherfigures. Sect-ionally it forms a T. g

A represents the skylight bars or rafters, each composed of two curvedplates arranged back to back curving or bent outwardly from each other.The plates are marked, respectively, a b. The upper curves of the saidplates form ledges or shoulders 0 c for the support of the glass plates13, and the lower curves of said plates in their hollows form gutters dd, which serve to carry off water resulting from drip or leakage, disehagin g the same at the .base by or through their lower ends intobase-gutter C of the base-frame of the structure at 1), from whence itis discharged through out-lets therein, as at E. The two curved platesmay be bolted together, or otherwise secured so as to form one bar, andthus used alone to form the skeleton of the structure.

At 0 is shown the under cap or molding giving finish to the under sideof the bar when desired, and its upper inside surface, which forms ahollow, constitutes an extra gutter, serving to catch and carry off anyleakage that might occur between the two plates forming the bar A.

At f is shown an upper cap, used whenever desired. It is composed ofpliable metal such, for instance, as lead-and is secured be tween thetwo curved plates of the bar, and, extending upward between the edges ofthe glass plates, is bent over the same when placed in position, and,flattened, forms a secure covering over the joints to prevent leakage.By the use of this cap, putty may be dispensed with, although I preferto bed the glass plates on putty placed between and above the upper Thusthe bar proper, A, may be used without the other device in combinationtherewith, or each of the other devices may be combined or all combinedtogether, to suit the desire of the purchaser or the size andnecessities of the structure.

At G is shown a ridge-bar for a skylight- .posed of narrow strips ofmetal which oftentimes are wasted, I propose to construct a very muchcheaper skylight than has hitherto been constructed, thereby filling amuch needed want viz, a metallic skylightat almost the cost of wood. InFig. 7 the pliable or lead cap-plate forms sectionally a T, extending asone plate down between the edges of the glass plates into the bar below,so as to be riveted between the two halves, and in this form may be usedwith or without internal strengthening-plates. This T-cap be readilyrolled into shape in long lengths and cut to any size required. It hasthe advantage derived from there being no joint in the transverseportion at the top, as is the case with the folded sheet of the otherfigures. \Vhat I claim as new, and desireto secure by Letters Patent ofthe United States, is-

1. A skylight bar or rafter, A, composed of two curved plates of sheetmetal, a b, placed back to back, bent to form ledges or shoulders c, forsupport of glass plates, and gutters d, for removing condensation andleakage, essentially as shown and described.

2. In combination with the bar A, formed, as described, of curved platesa b, bent to form ledges c and gutters d, the under cap or molding, 6,adapted to form a central or internal gutter, essentially as shown anddescribed.

3. In combination with the bar A, formed, as described, of curved platesab, having ledges c and gutters d, the cap f, of pliable material,arranged substantially as shown and described.

4:. .Incombination with the bar A, formed, as described, of curvedplates a I), having ledges c and gutters (I, one or more internalplates, 9, substantially as shown and described.

5. The combination of plates a I), (having ledges c and gutters (1,)caps c and f, and internal plates, 9, substantially as shown anddescribed.
